Among them, computers, as one of the most efficient production tools, have been widely used in all walks of life. There are also many types of computers. Portable laptops have more flexible applications due to their portability. However, due to their size, their own heat dissipation effect is average, and auxiliary heat dissipation is required when operating at high loads.

[0003] After searching, the Chinese patent publication number CN110275589A discloses a notebook cooling bracket, including a placement plate, a front end surface of the placement plate is symmetrically provided with a fan cavity opening forward, a filter is fixedly installed on the front inner wall of the fan cavity, a rotating mechanism that can rotate the placement plate is provided under the placement plate, and an adjustment mechanism that can adjust the height of the entire notebook cooling bracket is provided on the rear side of the fixed plate. The adjustment mechanism includes a fixed platform placed on the ground, and the front end surface of the fixed platform is rotatably installed to provide a rotating block for providing power to the adjustment mechanism.

[0004] The above patent has the following deficiencies: when the above device is in use, the laptop is supported by placing a plate, and then the angle is adjusted to dissipate heat, but the gravity effect caused by the laptop's own weight is ignored, which may cause it to slide downward, and this device does not have a structure to fix the laptop.
